Fix CI test failure: Make install-wp-tests.sh non-interactive

The script was prompting for user input when the test database already exists, causing CI to fail. This commit adds a check for CI environment ( variable) or non-interactive shell (! -t 0) and automatically proceeds with database recreation in those cases.

Fixes the Code Coverage Check failure on PR #700.
